A higher concentration of protons outside the inner membrane of the mitochondria than inside the membrane is the driving force behind ATP synthesis. D. carbon, nitrogen and hydrogen. answer choices . 30 seconds . Electron transport chain 1. During the electron transport chain, water and ATP are produced. It is a series of chemical reactions, broken down into three main stages: glycolysis, the citric acid cycle (or Kreb's cycle), and the electron transport chain. Lets Review: So far in Glycolysis, Acetyl CoA step, and Krebs we have made 4 ATP, 10 NADH + H+ , and 2 FADH2. (A). 0 0. Get more help from Chegg. Water is a by-product. A concentration gradient creates in which diffusion of hydrogen ions occurs by passing through ATP synthase.. NADH. Tags: Question 3 . Glycolosis: It is partial oxidation of glucose to form two molecules of pyruvate, two NADH, and two ATP. Become a Study.com member to unlock this Electron transport chain is defined as a series of reactions that involves transfer of electrons from one molecule to another via redox reactions and transfer of protons across the mitochondrial membrane. Q. The Electron Transport Chain and Oxidative Phosphorylation Produce the Majority of ATP. What are the products of the electron transport chain? Show transcribed image text. The electron transport chain contains a number of electron carriers. A higher concentration of protons outside the inner membrane of the mitochondria than inside the membrane is the driving force behind ATP synthesis. Now, the last step of the electron transport chain is you have two electrons-- and you could view it as the same two electrons if you like-- two electrons plus two hydrogen protons. Legal. Each chain member transfers electrons in a series of oxidation-reduction (redox) reactions to form a proton gradient that drives ATP synthesis. The electron transport chain: The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH 2 to molecular oxygen. Oxygen is a product of the electron transport chain. All rights reserved. No. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. The electron transport chain is the main source of ATP production in the body and as such is vital for life. Electron Transport Chain (ETC) is the moving of electrons through a series of electron transporters that undergo a redox reaction.Hydrogen ions accumulate in the form of matrix space with the help of an electron transport chain. The last step in the electron transport chain is when cytochrome a3 gives the electrons to oxygen. Cellular respiration is an aerobic process (requires oxygen) that is used to transfer chemical energy from food into ATP. 2 hydrogen ions and 2 electrons start the chain. Oxygen is a product of the electron transport chain. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. 30 seconds . SURVEY . Tags: Question 10 . The electron transport chain is a sequence of four protein complexes that incorporate redox reactions to create an electrochemical gradient in a complete mechanism called oxidative phosphorylation that contributes to the formation of ATP. Oxidative phosphorylation, incorporating two interdependent processes – the flow of electrons through electron transport chain down to the oxygen and chemiosmotic coupling-, is the final stage of cellular respiration.. Nutrition: From Science to You  (4th ed.). Which of the following is not part of the pathway... Balance the reaction between MnO2 and Cd to form... What type of reaction is cellular respiration? A. water, carbon dioxide and ATP. Water is a byproduct formed when oxygen accepts the electrons from the end of the electron transport chain and combines with protons. NADP is the final electron acceptor, NOT … 4. The products are ATP and NADPH (D). If 3 ATP/NADH and 2 ATP/FADH2 are used instead of 2.5 ATP/NADH and 1.5 ATP/FADH2 that were used above, total ATP and percentage of ATP produced by the electron transport chain would be different. For aerobic respiration, the electron transport chain or "respiratory chain" is embedded in the inner membrane of the mitochondria (see figure below). The electron transport chain comprises an enzymatic series of electron donors and acceptors. Describes the electron transport chain. C. dietary fiber and ammonia. A prosthetic groupis a non-protein molecule required for the activity of a protein. During the electron transport chain, electrons are passed on from complex to complex, and finally to oxygen, creating a proton gradient that will be used to make ATP.
